Analytic Solution of the Spencer-Lewis Angular-Spatial Moments Equations.

Abstract

An exact solution for the angular-spatial moments of the Spencer-Lewis equation is given, along with methods for reconstructing the electron density function. The new solution techniques is implemented in a computer code and several sample calculations are carried out with monoenergetic plane sources of electrons in infinite media of aluminum and carbon. The sample calculations produce the electron distribution in space and path length rather than some integrated quantity such as the energy deposition profile. Such analytic solutions are intended to serve as benchmarks for testing numerical electron transport codes. (Author)
